An integrated Internet camera system comprises a website archive and review center (WSARC) for storing and managing images and an Internet direct camera (IDC) for capturing an image, automatically transmitting the image to an account associated with said IDC on the WSARC upon image capture and receiving stored image from the WSARC. The IDC comprises a display for displaying the captured image and the received image. The IDC automatically connects to the WSARC over an Internet connection on power-up.

RELATED APPLICATION

The present application claims a priority to U.S. Provisional PatentApplication Ser. No. 60/702,470, filed Jul. 26, 2005, which isincorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to an integrated Internet camera and/orsystem that is simple to install, operate and maintain, moreparticularly to an integrated Internet camera and/or video system thatseamlessly and automatically transmits, receives, stores and/or archivesstill images, video and/or audio to and from a web site service/monitorcenter over the Internet using one or more integrated Internet cameras.

BACKGROUND OF THE INVENTION

The increasing use and awareness of the utility afforded by the Internethas transformed this simple image recording or capture process into amore complicated process requiring permanent storage and providing asecure centralized access to such storage from any remote location.

The currently available camera systems available are rigid andexpensive. These systems are complex and require a host of peripheraldevices to place an image on the Internet or Web. Additionally, thesesystems are bulky and not very portable. Moreover, the user must installone or more software to operate such camera systems. In a securitymonitoring application, these camera systems require a qualifiedoperator to operate and maintain such system.

An example of such prior camera system is shown in FIG. 1. In order foran operator to transfer the still image, video and/or audio file from avideo camera 100 to an account on the Internet or Web, the operator mustconnect the video camera 100 to a personal computer PC 200. The stillimage, video and/or audio file is transferred and stored in the PC 200before it is transferred or uploaded onto the Internet. That is, thecamera 100 must be connected to a network device (e.g., PC 200) beforeit can transmit or receive still image, video or audio files.

Some have attempted to resolve this problem by purchasing a network card(wired or wireless) to enable their camera 100 to connect to theInternet without a separate network device (i.e., PC 200). However, suchsolution is only available if the camera 100 can accept such networkcard and does not provide two-way access to the image file, i.e.,transmitting to storage and receiving from storage. Additionally, suchsolution generally requires the operator to install the network card andaccompanying software to “network” enabled camera 100.

Therefore, it is desirable to have an integrated Internet camera systemthat can seamlessly upload and download video and/or audio files to andfrom the Internet, transmits these files to another web-enabled portabledevice (e.g., another camera, a personal digital assistant (PDA), a cellphone and the like), receive/download video and/or audio files fromanother portable device and/or store/archive these files in a securewebsite without the necessity of connecting to another device, such as aPC 200.
